What I've often wondered is why they don't go back to the 1998 format? I realize the largest complaint was that the NHL didn't shut down for it and very few NHLers from those countries played. But having the final two qualifying rounds as the opening rounds of the actual Olympic tournament would be nice to see brought back.
I've often thought that part of the reason that the weaker teams are blown out is that they don't have time to gel as a team. I know it is an even playing field, but the weaker teams need help to be competitive. By playing an opening round as part of the Olympic tournament, this would help them gel as a team and perhaps after 3 games, might not be lambs led to the slaughter as in the past.
As for Japan at the Worlds, they didn't pay to be there. If I remember right, the IIHF attempted to grow the game in Asia by holding what they called the Far East Qualification Tournament every year, guaranteeing the winner a spot in the main draw. Since it really didn't spur hockey to greater heights in Asia as a result of it, they stopped doing it. If I remember right, it was always Japan that qualified and they usually blew out the other teams participating in that tournament.
I know the NHL would never commit to something like this, but I would like to see Olympic qualifying resemble World Cup of soccer qualifying. There is no guaranteed spots except for the host and everyone must win their way in. You weight the continental groups, so that it is fair. I would say North America should get 1 automatic spot and Europe 3. The second stage would see the second place North American team, the winner of Asia, some number of European finishers and perhaps the winner of an African/South American/Oceania tournament play for the remaining spots.
The North American tournament, could feature a double round robin (as I assume only Canada, US and Mexico would participate) format and the top two (I assume Canada and the US) would then play a best of 7 tournament for the North American spot. This could be spread over a two summer period.
But the point would be the United Arab Emirates has just as much of a chance of making the Olympics as Canada. Of course, generally much like World Cup of soccer qualifying, the Faroe Islands of the world are gone fairly quickly, but it would be interesting to see the mix of teams that might come out of this. You could see a shocker where say Denmark gets in but Russia does not. Also, by only granting North America one spot for the champion, it does mean that in theory either Canada or the US could fail to qualify.
